The bald man with a tattoo on his right arm sat with his hands in his lap as his matter was heard.

As he was charged with murder, the officer was unable to apply for bail until the hearing reached a higher court.

He was remanded in custody for the charge to be heard again on March 14. He will not be required to appear.

Senior Constable Randall's solicitor, Craig Pratt, asked that a brief of evidence be prepared as soon as possible given the lengthy investigation.

Police commissioner Ian Stewart described the allegations as a "really tragic circumstance".

"I have known for some time that the investigation is on foot, but like many of these particular types of investigations, a normal murder investigation is tough enough, but when it is a child, particularly an infant, as it is in this case, there are other complexities, particularly around the medical side of things," he said.
